AUTOMATIC FILLIN G-REPLENISHIN G LOOM.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed September 25, 1911. Serial No. 851,068;

Salem, county of Essex, State of Massachusetts, have invented an Improvement in Automatic Filling- Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to looms of the type automatically with filling from time to time. and the invention is particularly applicable to looms of that type wherein the operation of the filling replenishing mechanism is brought about by the usual action of a filling fork when the filling breaks or runs out.-

When the filling runs out as the shuttle enters the box at the replenishing, side of the loom the spent filling-end extends from the selvage of the cloth toward the replenishing shuttle box. On the next pick of the shuttle the absence of filling is detected by the fork, and on the second pick the fresh supply of filling is inserted in the shuttle if the latter be properly positioned in the box at the replenishing side of the loom.

When the replenished shuttle is picked there is always a tendency to carry the spent filling-end back into the cloth, making a fault therein.

My present invention has for its object the production of simple, effective means for withdrawing the spent filling end from the path of the shuttle as soon as possible to obviate the faulty action above referred to.

The novel features of my invention will be described in the following specification and particularly pointed out in the claims annexed hereto.

Figure 1 is a top plan view of a suflicient portion of a filling replenishing loom at the replenishing side with one embodiment of my invention applied thereto, the parts being shown in normal'position; Fi 2 is a transverse sectional detail on the l1ne 22, Fig. 1, looking to the right.

The lay A having a shuttle-box B at the replenishing end thereof, the hunter C on the lay, see Fig. 2, the hopper or filling feeder F for the reserve supply of filling carriers or bobbins, the transferrerrf, the

controlling rock shaft d by or through which the operation of the replenishing shuttle is replenished mechanism is controlled, the shuttle-feeler 3/ fulcrumed at a, Fig. 2, andnormally held in inoperative posit-ion by the arm d" fixedly attached to the controlling rock shaft (2, and the dog m movable into position to be engaged by the hunter (3 when filling replenishment is called for, may be and are all substantially as in United States patent to Northrop No. 628,228 patented July 4, 1899, the function of the shuttle-feeler being to prevent the operation of the replenishing mechanism if the shuttle is improperly positioned for replenishment in the box B. In

Fig. 1 I have shown a thread-cutting temple T of a well known form, such for instance as shown in the patent to Draper and Stimpson N 0. 585,465 dated June 29, 1897, said threadcutting temple being arranged to cut a filling-end close to the selvage of the cloth at the replenishing side of the loom.

Referring to Fig. i it is supposed that the filling has run out as the shuttle enters or is about to enter the shuttle-boxB, leaving a spent filling-end 15 extending from the selvage of the cloth toward the shuttleboX. The shuttle, however, is supposed to have been picked thereafter to the opposite side of the loom. Near the mouth of the shuttle-box, in accordance with my present invention I form a transverse recess 5 in the lay across which recess lies the spent filling-end t and to the shuttle-feeler y I have fixedly attached a laterally and inwardly extended arm 6, said arm at its free end being upturned at 7, Fig. 2, and then rearwardly at 8, the upper edge of the extension 8 being transversely notched as at 9. This notched extension constitutes a thread retractor so positioned with relation to the recess 5 that when the shuttle-feeler is moved into operative position across the mouth of the shuttle-box, see dotted line position Fig. 2, the retractor will pass into the recess 5 beneath the spent filling-end t.

It will be well understood by those skilled in the art that the detection of filling absence takes place on the pick of the shuttle to the left from the box B, and on the re turn pick the shuttle-feeler and thread retractor will be operatively positioned, supposing the shuttle to be properly positioned for replenishment, so that as the shuttle feeler returns to its normal position the retractor will engage and draw away spent filling-end at from the shuttle path ico the

into substantially the dotted line position t", Fig. 1. Consequently, as the shuttle with the fresh istlpply of filling is picked from the box 3- the spent filling-end will be retracted or withdrawn from the path of the shuttle, and the tendency of the latter to draw such filling-end into the cloth will be obviated. v

The retractor not only draws the thread away from the shuttle path, but it also hastens the action of the temple threadcutter upon the spent filling-end, for by inspection of Fig. 1 it will be noted that the dotted line position t" of the spent'fillingend is ,such that the temple thread cutter can readily act upon the same and sever it close to the selvage. 7

After the spent filling-end is cut by the temple threadcutter the filling-end will hang from the retractor '8 instead of droppifigon the lay. By mounting the retractor on the shuttle feeler the movement of said retractor into and out-of operative position is readily effected, and at the proper time for if the shuttle is properly POSltlOIlGd'SO that the replenishing mechanism can operate the thread retractor will also be properly positioned to engage and draw the spent filling-end away from the shuttle path.

Having fully described my invention,

what I claim as new and desire to secure by Letters Patent is:

'1. In an' automatic filling replenishing loom, in combination, a lay transversely recessed near the mouth of the replenished shuttle-box, a shuttle feeler to prevent filling replenishment when the shuttle is improperly positioned, a thread cutting temple at the replenishing side of the loom, a laterally and inwardly extended arm fix edly attached to the shuttle-feeler and upturned at its free end, and a rearwardly extended thread retractor forming a continuation of the upturned part of said arm, movement of the shuttle-feeler into opera- -tive position when filling replenishment is called for causing the retractor to enter the recess in the lay'beneath and to engage a spent filling-end, return movement of the shuttle feeler andretractor to normal position drawing the spent filling-end out of the shuttle ath and into .position to be acted upon the upper edge of the retractor having a series of notchesto engage the thread.

2. "In a loom 1n combination, a lay having a shuttle-box, mechanism to replenish the shuttle automatically with filling when properly positioned in said shuttle-box, a rearwardly extended thread retractor notched on its upper side and movable in a fore and. aft direction into position to engage a spent filling-end between the cloth and the mouth .of the replenishing shuttlebox when'filling' replenishment is to be effected, and a shuttle-feeler on which the retractor is fixedly .mounted to move said retractor into and out of operative position when filling replenishment is efiected, movement of the retractor to normal position operating to withdraw a spent filling-end from the path of the shuttle to thereby prevent saidfilling-end from being woven into the clothby'the shuttle after replenishment;

' In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
